Area Forecast Discussion . UPDATED National Weather Service Austin/San Antonio TX 1031 AM CST Wed Feb 24 2021

UPDATE. Morning clouds are still lingering around across most areas. Temperatures are already in the lower 60s to lower 70s ahead of a cold front. The frontal boundary is currently located along a Pandale to Junction to Burnet line based on visible satellite and surface observations. This front will slowly push across the area for the rest of today with skies clearing from northwest to southeast for the most part. Highs are forecast to range from the upper 70s across the Hill Country to lower 80s across the southwest counties. Dry conditions are expected through late tonight with only slight to low end chances for rain across the southeast part of South Central Texas. A cool airmass follows with overnight lows in the mid 40s across the northern parts and mid 50s to lower 60s along and south of Highway 90. Moisture and clouds return overnight as isentropic ascent takes control with southerly winds dominating just above the shallow cold front. By Thursday morning, increased low level moisture will stay over the area with cloudy skies expected all day on Thursday and chances for rain are possible mainly along and east of Highway 281. Thursday's highs in the 50s and 60s over most locations.

PREV DISCUSSION. /ISSUED 552 AM CST Wed Feb 24 2021/

AVIATION . MVFR ceilings continue at the I35 sites with VFR visibility. South winds remained breezy for most of the night which kept the ceilings elevated a bit, but speeds have weakened a bit and the ceilings should lower into IFR categories for at least the San Antonio sites shortly. VFR will return this afternoon with north winds as a weak cold front moves into the area. Another round of MVFR ceilings is expected tonight.

PREV DISCUSSION . /ISSUED 346 AM CST Wed Feb 24 2021/

SHORT TERM (Today through Thursday) . Low clouds overspread the eastern two-thirds of the forecast area this morning. South/southwest winds around 10 mph with higher gusts is keeping any fog at bay for now, but may still see some drizzle or patchy fog by sunrise. A weak cold front is currently located in the Texas Panhandle and northwestern Oklahoma and will continue to push south through the morning hours. Current timing has the front making it into the Edwards Plateau and northern Hill Country around noon. Don't expect the front to do much temperature wise today with highs well above normal, near 80 degrees for much of the area. This will be about 10-12 degrees above normal.

The front will be slow moving as it arrives and should finally be near the southern border of the CWA by midnight. As it moves south of the area, we should see some isolated showers develop behind the front across the Coastal Plains late tonight and will mention a 20- 30 percent chance of rain there. Lows tonight will be cooler, in the 40s in the Hill Country and in the 50s across much of the remainder of the area.

For tomorrow, north winds will continue as the front remains stalled just to our south. Weak overrunning conditions will continue and encompass much of the area with areas east of the I-35 corridor having the higher probability for the light shower activity. Highs tomorrow will be in the middle 50s to near 70 degrees with the cooler values in the Hill Country and Edwards Plateau.

LONG TERM (Thursday Night through Tuesday) . The stalled front to the south will keep lingering shower activity, mostly in the eastern counties, and cloudy skies in the area friday morning, before shifting west to east by Friday evening. Highs Friday will be in the 60s and just a few degrees below normal. Southerly flow takes back over at the start of the weekend and with it comes warmer air and increased moisture. This will keep a chance for showers remaining in our eastern counties in the afternoons, through the remainder of the forecast period. Highs stay above normal through the weekend, while the remainder of the period stay near normal.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
